With reference to water vapour, which of the following statements is/are correct?

1. It is a gas, the amount of which decreases with altitude.
2. Its percentage is maximum at the poles.

Select the answer using the code given below :

(a). 1 only

(b). 2 only

(c). Both 1 and 2

(d). Neither 1 nor 2

 

Explanation:

Statement 1: Correct. Water vapor is indeed a gas, and its concentration generally decreases with altitude due to lower temperatures and pressure at higher altitudes

Statement 2: Incorrect. Water vapor content is generally higher in warmer regions, near the equator, and decreases towards the poles due to lower temperatures.

Therefore, the correct answer is (a): 1 only
